Abstract Polymer matrix composite with inorganic fillers, can generate new properties and functionalities. In this paper, a silicone modified acrylic resin-based (Si-MA) nanocomposite that has a high thermal conductivity and a good corrosion protection was prepared. We found that the graphene nanosheets (GNS) and carbon nanotubes (CNT) can be uniformly dispersed into Si-MA after surface modification with N,N’-(cyclohexa-2,5-diene-1,4-diylidene)bis(2-hydroxy-N-(2-hydroxy-3-(4-(trihydroxysilyl)butoxy)propyl)-3-(4-(trihydroxysilyl)butoxy)propan-1-aminium) (TSiPD). The introduced the functional silanol hydroxyl groups result in good interfacial bonding between the nanofillers and Si-MA. The Si-MA nanocomposite with 9.9 wt% modified GNS and 0.1 wt% modified CNT shows a high thermal conductivity of 2.97 W/(m·K), which is caused by the formation of a honeycomb structure made of 2D GNS and 1D CNT, and the decrease of the interface heat resistance. Moreover, The Si-MA nanocomposite with 9.9 wt% modified GNS and 0.1 wt% modified CNT demonstrates good corrosion protection, which is caused by the good mechanical properties, hydrophobic performance and efficient barrier effect of the nanocomposite fillers. This nanocomposite coating has great potential application in the field of heat exchange corrosion protective coating for the heat exchangers.

摘要 聚合物基复合材料与无机填料，可以产生新的性能和功能。在本文中，制备了一种具有高导热性和良好防腐保护的有机硅改性丙烯酸树脂基（Si-MA）纳米复合材料。我们发现石墨烯纳米片 (GNS) 和碳纳米管 (CNT) 在用 N,N'-(cyclohexa-2,5-diene-1,4-diylidene)bis(2) 表面改性后可以均匀地分散到 Si-MA 中。 -羟基-N-(2-羟基-3-(4-(三羟基甲硅烷基)丁氧基)丙基)-3-(4-(三羟基甲硅烷基)丁氧基)丙-1-胺) (TSiPD)。引入的官能硅烷醇羟基导致纳米填料和 Si-MA 之间良好的界面结合。具有 9.9 wt% 改性 GNS 和 0.1 wt% 改性 CNT 的 Si-MA 纳米复合材料显示出 2.97 W/(m·K) 的高热导率，这是由 2D GNS 和 1D CNT 构成的蜂窝状结构的形成以及界面耐热性的降低引起的。此外，具有 9.9 wt% 改性 GNS 和 0.1 wt% 改性 CNT 的 Si-MA 纳米复合材料表现出良好的防腐蚀保护，这是由于纳米复合填料具有良好的机械性能、疏水性能和有效的阻隔效果。该纳米复合涂层在换热器换热防腐涂层领域具有巨大的应用潜力。纳米复合填料的疏水性能和有效阻隔作用。该纳米复合涂层在换热器换热防腐涂层领域具有巨大的应用潜力。纳米复合填料的疏水性能和有效阻隔作用。该纳米复合涂层在换热器换热防腐涂层领域具有巨大的应用潜力。
